Reducing arsenic

Responding to growing concern surrounding the safety of arsenic in drinking water, Ft. Washington, Pa.-based Severn Trent Services Inc. has introduced a new line of products that will dramatically reduce concentrations of arsenic from a variety of water sources. While many health and environmental organizations are calling for a reduction of arsenic to a level of 10 parts per billion (ppb), the new SORB 33 process consistently achieves levels below 5 ppb.
